这些钥匙是谁的who does these keys belong to?还是Who do these keys belong to?Whom does these keys belong to 那句对

who does these keys belong to？这个应该是对的
后一句是谁做的！！

who（whom）do these keys belong to？是对的these keys为复数，应用do。
希望对你有帮助

为你解答。
这些钥匙是谁的？
Who do these keys belong to？
解释：后一句是对的。主语the keys是复数，助动词应该用do，而不是三单形式does。疑问词who是作为belong to的宾语。

后面那个 因为keys 是复数

Who does these keys belong to ?主语是谁 所以用does

主语是These keys, 所以要用do。 另外谓语是who, 严格的语法里面应该用whom
Whom do these keys belong to?

who（whom）do these keys belong to？是对的these keys为复数，应用do。
望采纳，谢谢

Who do these keys belong to 对,因为主语是复数（these keys ),其实,who 也可用whom

最简单的不应该是 Whose these keys吗?

直接问：
Whose keys are these?
表示这些钥匙是谁的？
